Yep--I'm going to return it, especially now that I just bought 2 GTS 250s that, after Bing and 2x $80 rebates, will just cost me $70 or so.

You would have copied the end of the fahlog.txt file.

Yea--I'm not sure how the VM works either. I guess I'll figure it out in a few days.
Copy it from the log in fahmon, then paste it in the thread.

The FAHMon log only shows the progress, doesn't it?
Open up fahmon, click View -> Show/hide fah log. Click on the i7 client and it should show the entire log.

True. But it only shows the progress of the work unit in a percentage.?
How would this have helped decide for, or against an SSD?
He wanted to see how long it takes to go from a finished unit to a new unit. Apparently a lot of data is written to the hard drive.

Ahh, ok.

Apparently I'm just going to run a portion (500-750MB) of ram as a hard drive--it speeds up the final write process that takes a long time usually for computers because it's a whole lot of tiny files.

I know we're past this, but I thought I'd post it anyway.
Is this what you were looking for?
Looks like it took an hour and twenty minutes from the end of one unit, until it started the next.

What is your internet upload/download? Looks like it's taking 30 minutes for that--which you probably can't really change. However, if you end up with extra ram sometime to make a Ram disk in Linux, you could cut the 25ish for writing to disk down a lot...maybe more like 5 minutes.

Fastest I can get in my area.
How much RAM do I need? Now much I hope. lol
I believe the setup I found makes a 500MB ram disk that expands as needed (it doesn't need more than 750MB). However, though, if you lose power, you lose the entire work unit--so you'd need a solution for that.

How or why would I lose power?
Jet

If the power blinks
(I never experience it, but apparently some people are concerned about it).EDIT: By the way--can you overclock that i7 more? You should get closer to 3.8, I'd think.

Ahh. That rarely happens here.
How do I set it up?
